Which, do you know how much way more advanced science go on inside of those chips in order to create them? The issues you mention are a logistical nightmare, and due to the costs involved it currently isn't lucrative to reclaim them from built devices. Let's say that someone was willing to pay $1,000 for one entirely boring, through-hole 74-series logic chip. Would that change the calculus on it being "too hard" to put them back in the supply chain? Junk VCRs in the garage would suddenly be potentially worth a several thousand dollars each! At a thousand dollars per chip, it would be worth my time, personally, to do the testing and clean up, and for someone at the other end to verify I've actually done that, and that the chips are functional.

That astronomical price is obvious fantasy, but it's not too difficult as a task, it's that capitalism can't and won't care about the environment until after it's too late (which, it might already be).
